From an article on cleveland.com —
From 4 to 8 p.m. on Feb. 10-14, the deck will greet guests for a charity fundraiser in support of St. Jude Children’s Hospital. Tickets are just $5 and a portion of the proceeds from sales will be donated to St. Jude.
Guests will get to take a self guided-tour of the 42nd floor (the Tower has 52 floors, but the deck is on 42).
Tickets are available in 30-minute increments. No walk up tickets will be sold. Advance tickets must be purchased HERE.
